外文摘要：Efficient nanoporous amberlite (XAD-4) based solid strong acid (XAD-4-SO3H-SO2CF3) has been successfully synthesized by decorating SO2CF3, a strong electron withdrawing group onto the network of nanoporous solid acid of XAD-4-SO3H. N-2 sorption isotherms and TG curves show that XAD-4-SO3H-SO2CF3 has large BET surface area and good thermal stability. XPS spectra show that the group of SO2CF3 has been introduced onto the network of XAD-4-SO3H. TEM results shows that the well-dispersion of C, S, and O elements. Catalytic property tests show that XAD-4-SO3H-SO2CF3 exhibits excellent catalytic activities in biomass transformation toward acylation of anisole with acetyl chloride, synthesis of bisphenol-A and esterification of acetic acid with cyclohexanol when compared with those of solid strong acids of Amberlyst-15, SBA-15-0.1-SO3H, H3PW12O40 and XAD-4-SO3H.
